This invention relates to cigarette rod sealing surface extending along the cigarette rod and engaging the same to press together and smooth the freshly pasted overlapping.

edges of the paper strip. .VEXCGSS paste accumulates on the sealing surfacewhich must be periodically removed to prevent the eX- cess from smudging the rod. With prior sealers it has been necessary to stop production while the sealer was being cleaned. The object of this invention'is to avoid this loss of production by providing sealing mechanism which can be cleaned without holding up the operation of the machine. Tothis end it is an object of the invention to construct a rod sealer which has separated sealing surfaces so mounted that one may be cleaned while another is in action and vice versa. 1

With these and other objects notspecifically mentioned in view the invention consists in certain constructions and combinations which will be hereinafter fully described and then specifically set forth in the claims hereunto appended.

In the accompanying drawings, which form a part of this specification and in which like characters of referenceinclude the same i or like parts, Fig. 1 is aplan view partly.

broken away of a sealer'constructed inv accordance with the invention; Fig. 2 is a side elevation partly in section of the device shown inFig. 1 and Fig. 3 is a sectional end elevation on the line 3-3 of Fig. 2.

In carrying the invention into effect there is provided a rotatable support extending along a traveling cigarette rod, together with two supported sealing bars carried by said support with one engaging the'seam of the rod and with the other in position to be cleaned while the engaged bar is'in action.

cated at diametrically opposite positions on said support.

Referring to the drawings, a bracket 10 attached to the frame of the cigarette machine carries a stud 11 on which is pivoted a forked arm12 having aligned bores in which is rotatablyv mounted a tubular suppo-irt 13 I extending along the cigarette an o with its sealers. These sealers are provided with a axis parallel to the rod. A knob 14 on the "end of the tube facilitates turning the tube to reverse the sealing surfaces supported thereon as described below. I

Two'spaced sealing bars 16 are secured 111 slots of a frame 15 fixed to the tube with the sealing surface of the bars atdiametrically opposite positions with respect to the axis of the tube 13; 1 A heating element 1'? within the tube serves to heat the-sealing bars.- A guard 19' is pivoted at 18 on the arm 12.

Conduction ofheat from the tubetothejarm :12 is retarded by heat insulating bushings.

20 and 21 in the'bores thereof. ;The supporting tube 13 is held with the bars ineither one of their two positions with the bar which is in operating positionproperly located relative to the rod by means, of a ball 22 in the arm 12'. pressed by a spring 23-and nut 24: into eitherflone of two diametrically opposite notches inithetube. A set screw 25 inftlie arm '12 regulates the sealing pressure.

Therod C carried in the direction of the arrow in Fig. 2 bythe usual driving'tape 26, issues from the rod former 27, 28 where paste 'is applied andthe rod closed, intofcontact with one of the bars 16, which presses and smooths the seam and driesthe paste. /Vhen paste accumulates thereon the knob? 14' may be quickly turned to a position in which the ball 22 snaps into the opposite notch. The guard 19 can then be lifted and the upper bar cleaned at the o era-tors convenience during the operation of the machine.

VVhat is claimed is: v

1. The combination with a rotatablesupport extending along a traveling cigarette rod, of two separated sealing bars carried by saidsupport with one engaging the seam of the rod and withthe other in vpos1t1onto be cleaned whilethe engaged'bar is in action. In the best co-nstructlons these bars are lov2. The combination witharotatable support extending along a traveling cigarette rod, of two separated sealing bars carried by said support with one engaging the seam of 3. The combination with a rotatable support extending along a traveling cigarette rod, of two separated sealing bars carried by said support with one engaging the seam of the rod and with the other in position to be cleaned while the engaged bar is in action, and means for heating said support and said bars.

4. The combination with a rotatable support extending along a traveling cigarette rod, of two separated sealing bars carried by said support with one engaging the seam of the rod and with the other in position to be cleaned while the engaged bar is in action. and a frame carrying said support and bars and movable in and out of operative position.

5. The combination with a frame, of a rotatable support thereon, a pluralityol spaced sealing elements secured on said support in position for movement therewith into operative engagement with the rod, and means for holding said support in any one of a plurality of predetermined positions in each of which one of said surfaces engages the rod and another is in position to be cleaned.

6. The combination with a frame, of a rotatable support thereon, a plurality of spaced sealing elements secured on said'support in position for movement therewith into operative engagement with the rod, and means for holding said support in any one of a. plurality of predetermined positions in each of which one of said surfaces engages the rod and another is in position to be cleaned, said means comprising a spring pressed ball and a cooperating notched surface.

7. The combination with a frame, of a rotatable support thereon, a plurality of spaced sealing elements secured on said support in position for movement therewith into operative engagement with the rod, and means for holding said support in any one of a plurality of predetermined positions in each of which one of said surfaces engages the rod and another is in position to be cleaned, said sup port comprising a cylindrical element axially rotatable in said frame and a slotted holder secured about said cylindrical elemen t, said sealing elements being secured in the slots of said holder.

8. The combination with a frame, of a rotatable support thereon, a plurality of spaced sealing elements secured on said support in position for movement therewith into operative engagement with the rod, and means for holding said support in any one of a plurality of predetermined positions in each of which I one of said surfaces engages the rod and another is in position to be cleaned, said support including a tube journaled in said frame, and a heating element in said tube.

In testimony whereof, we have signed our names to this specification.
